TO AIiIi PERSONS TO WHOM THESE ]?R.`E lSlll\l"lS MAY COME.: t Be it known. that I, EDWARD FITZHENRY, of, Boston, in the 'county of Suffolk, and State 'of Massachusetts, have made a new and useful invention havingreterenceto Machinery for Dressing or Scouring or Setting Out Iieather; and do hereby declare the salue to be fully described in the following specication, and represented in the 'accompanying drawings, of whichf Figure 1 is a top view,

Figure 2 a side elevation, and.

Figure 3 a longitudinal section of a leather-s .upportin g tablet and its sustaining-devices. Figure 4 is a vertical section of one' of the casters, its socket-piece, and adjusting-screw, as employed for the support of the tablet. i I i Letters Patent, No. 62,234, dated February 26, 1867, have beenv grantedA to me for th'e employment, in'a l machine iorscouring4 and sleeking or setting-out leather, of anti-friction balls, or their equivalents, for the pur pose of supporting the tablet-of such machine.

' Diiculties-haveoccurred in the practical operation of the said improvement. It presents no means of adjusting the balls to the lower surface of the tablet. Furthermore, the liquid from the tablet, by running into the cups or bearings of the balls, carries with it matters which cause thel balls frequently to adhere to their cups, or work unevenly therein. Furthermore, the balls are liable to wear the bottom of the tablet in grooves.

In' carrying out my present invention, I substitute for the balls a series-oi` inverted furniture-casters, they or' their socket-tubes being fixed in the radial bars of the supporting-frame, and each being'provided with an 'adjusting-screw, or its equivalent, so applied to the socket-tube or piece, and the spindle or journal of the wheel o the caster, as to be capable Aof eiecting the vertical elevation or depression of -such spindle and wheel, so as to force the latter into contact with the table, as occasion may require.

Each of the caster-wheels is'notV only capable of being revolved on its own' axis, but of lbeing revolved in a circular path about the axis of its spindle, such being eiected by moving the tablet in various directions, horizontally, upon thefseries of casters. The wheels, when having dat insteadofcurved perpheries, and being capable of'a compound movement, as described, will not wear into the tablet in grooves, as the spheres or balls are liable to do when used.4

The casters enable the tablet to be moved very much easie'r .than it canvbe when resting on` balls, for the leverage of each caster 'on which the tablet may rest is brought into play to excellent advantage to facilitate the movement of the tablet. The casters are more than mechanical equivalents lfor the balls, because'the former, besides accomplishing the 'effect of the balls, produce new results, and overcome d-ifculti'es incident -to the balls.

In the drawings, Aidenotes the tablet, B a post, surrounded by a series of other posts, C C C, from the tops of which to that of the post B, a series of bars, DD D, extends horirontally.l

The casters, as inverted and appliedto su'ch bars, are exhibited vat E E E; 8m., a being the socketetube or piece, b the wheel, and c the spindle of each casteri The adjustingfscrew, on which the lower 'end of veach Vspindle rests, is shown std as screwed u`p through the bottom of the socket-piece.

I would remark that I usually provide the spindleiot' each caster with an annular cap, to encompass it just above the upper end ofthe step or socket of the spindle, and toV completely cover the tcp of 'such socket, the same being in order to prevent liquid,'when discharged from the tablet, .from falling upon and running into the socket-piece of the spindle.

lI do not herein claim the subject ofthe patent hereinbeiore mentioned, nor do I claim a furniture-caster as commonly constructed, but

What I do claim in aileatherlscouring or sleeking machine iis-- The combination of a series of casters, E E, &c., in manner substantially as set forth, with the tablet and its supporting-frame, the whole being substantially as described.

`And in combination with o. series of casters, a. tablet and a supporting-frame, arranged and composing parts of machine, a-s undfor tbe prpose described; I claim an udj'usting-screw, or its equivalent, applied V1o each or any of such casters, for tbe prpose of effecting the adjustment of' the caster-wheel, or the same und its spindle,'wth referenee to the tablet, in manner as explained.
